Make first of all a very thick white sauce of flour, milk, and butter, not forgetting also salt and pepper; when it is very thick add grated GruyÈre cheese, in the proportion of a heaped teaspoonful of this to a breakfast-cupful of sauce. Take it off the fire, and stir in first of all the juice of a lemon, and then the yolk of an egg. Let it get cold. Then mince up finely your veal, or, indeed, any lean meat. Mix it well with the sauce, and make croquettes of it. Then roll each in the white of egg that you have left, and then in grated breadcrumbs, and fry in deep fat.
